To aZZ whom t may concern.'

Be it known that we., GEORGE F. Sis- BownR, a citizen-of the United States, residing at Flushin in the county of Queens and State of New gYork, and Louis E. PrrToNI, a subject of the King ot lltaly, residing at New York city, in the county of Queens and State of New York, have invented certain new and useful improvements in Convertible Beds, the following being a full, clear, and exact disclosure of the one `t'orln of our invention which we at present deem preferable.

For a detailed description of the present form of our invention, reference may be had` to the following specication and to the accompanying drawings forming a part thereof, whereinl@ ig. lis a side elevation of the framework of our device;

F ig. 2 is a plan of one end of the mattress wire fabric;

Fig. 3 shows the open or distended position of the frame, and

Fig. 4l shows it in an'intermed'iate position.

Our invention resides in a folding or convertible bed that may be made into a chair for day 'use-a davenport being considered as a wide chair. To this end we provide three frames, one of which forms theback of the chair and also an approximate third of the bed; while the other two frames are nested one within the other to form 'the seat of the chair but are opened out away from each other to form the other twothirds of the bed. lin particular, we have devised a special form of -link-and-lever connection for these frames which we have found to be superior in most respects to any nowv known to us, especially as regards ease and certainty of operation, also simplicity, strength and cheapness of construction.

Referring to the drawings, A represents the middle or seat-frame; B the extension frame' wherein the seat-trarne` is nested when the chair is formed', and C the trame which forms the back of the chair or one I end of the bed. D represents a deep U-bar which at each end of the bed is pivoted at. its outer ends to the inner edge of frame B,

and at its inner part which 1s widenedVor branched by brackets all d2, it is movably connected at two points to two other points' l frame Specication of Lettersatent. Pabmliljgd Jun@ 1233, 11922,

on the horizontal cross-bar A2 of trame A. by means ot two crossing links X- and Y. The widening brackets d1 anda?2 are riveted to-the inside of each leg of the U-bar D, as is shown in Fig. 2. 'llo one end of each link X and 'Y is connected a spring, the twosprings being denoted by l and 2, and these springs are connected at their opposite ends to the aforesaid cross-bar A2. rllhe springy l resists the movement Iof link X around its point of connection with the cross-bar when the trame B is coming to its extendedI position, shown in Fig. l, while sprin 2 acts similarly on link Y when trame is coming to its closed or nesting position, shown in. lF ig. 1. By this arrangement the springs aid the start and resist the nish of ,both movements. llt requires but a slight push to start either the o ening or. closing while the nish of bot movements is cushioned so as to'bring the parts gently to rest. The U-bar D not only serves as the connecting agency between the frames A.' and B but also serves as a side bar for trame B to resistthe longitudinal pull of the wire mattress fabric.

The back frame C is jointed directly to one corner of the frame A and is curved,

downward at its innerend. To this inner end is pivoted one end of link F, the other end of this link being pivoted to the aforesaid bar D at a point somewhat more than half wa down from its outer end. yThe is also provided with pivoted le'gs ea"'c`h of which is o erated by a link G which acts to draw the deg in close to the back, as shown in Fig. l when the frames are closed together to form a chair. Each of the three vtrames A, B. and C is provided individually with a wire mattress fabric as shown in Fig. 2.

What we claim as new and desire to 'secure by Letters Patent is:

l. A convertible bed 'comprising two frames which may be nested to form a seat, an intermediate lmember at eachy end of the seat plvoted at one side to a point onv one frame and at its other side widened and connected to the other frame at two points by means of links, springs for aiding the start vand retarding the finish of both opening ,and closing movements anda third trame ormin a back for said seat, the third trame p1voted to oneofl said' nesting frames and linked to the said intermediate member.

2. A convertible bed comprising two frames which may be nested to form a seat, an intermediate member at each end pivoted to one point on one of said frames and connected by links to two points on the other frame, springs for aiding the start and resisting the finish of both opening and closing movements together with a third frame pivoted to one of said nesting frames to form a back for the seat and linked to said intermediate member.

3. A convertible bed comprising two frames which maybe nested to form a seat, an intermediate member in the form of a U- bar the ends of which are jointed to one oit' the said frames, links at each end of the seat connecting two points on said member to the other frame, a third frame formin a back for the seat and linked to said mem er and springs acting to aid the start and retard the finish of both opening and closing movements.

4. A convertible bed comprising two frames which may be nested to form a seat, an intermediate member in the form of a U- bar constituting a strut for one side of one of said frames and jointed thereto at its ends, brackets on said member, links joining said brackets respectively to the other frame a third frame forming a back for the seat and linked to said member and springs acting onsaid links to aid the start and resist the finish of both opening and closing movements.
